LUBRICANT-RETAINER.

Specification of Letters Patent. Patented J 11 16, 1914,

Application filed May 17, 1909. Serial No. 496,675.

To all whom it may concern.

Be it known that I, JoI-IN EDWARD THE- nnm), a citizen of the UnitedStates, residing at Buflalo,'in the county of Erie and State of NewYork, have invented certain new and useful Improvements in Lubricant-Retainers for Contacting Bodies, One Within the Other, Forming aBearing. The relation of said improvements to contacting bodies forminga bearing, but one terminating within the other, forms the subject ofLetters Patent No. 958,193, issued May 17, 1910. The relation of saidimprovements to contacting bodies, one within the other, forming abearing, but not terminating one within the other, forms the subjectofthis application; and I do hereby declare the following to be a full,clear, and exact description of this improvement, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to figuresof reference marked thereon, which form a part of this specification.

The object of that part of my invention which forms the subject of thisapplication is toprovide similar means between and at lubricant. To thatend, I provide one or more rings or devices placed between the saidbodies, at or near each end'ofthe contacting surface of said bearing andhaving said rings or devices fixed upon the outer of said bodies andforming with said bodies one or more annular spaces between the saidbodies, while allowing a free working fit between the said bodies andbetween the inner of said bodies and said rings or devices. Occupyingthe said annular space or spaces, I provide one or more rings or devicesfixed upon the inner of the said bodies and having a free working fitwith the outer of said bodies and said rings or devices thereon; allparts being so arranged that, if the lubricant should pass out betweenthe said bodies and rings or devices at or near each end of thecontacting surfaces of said bearing, it would, of necessity, pass aroundthose rings or devices fixed upon the inner of said bodies, first awayfrom, then parallel with, then toward the axis of rotation and then outfrom between the said bodies; but in amotion of rotation between saidbodies, the said lubricant would be prevented from returning toward theaxis of rotation by centrifugal action and thus prevent the escape ofthe lubricant and demonstrating the retaining qualities of my invention.

My invention further consists of certain details of construction, all ofwhich will be hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal sectional view of a journalbearing fitted with my invention. Fig. 2 is a longitudinal sectionalView of another journal bearingfitted with my invention but having oneset of rings or devices, according to my invention, at one end of thecontacting surfaces of said bodies forming a bearing, while at the otherend I have two sets of rings or devices. Fig. 3 is a perspective andsectional view of a tight and loose pulley on a shaft supported inhangers together with the assembled parts of my improved lubricantretainer. I

Referring to the drawings, in Fig. 1, 1 is a shaft or journal free torotate in the journal bearing or box 2. 3 is a lubricant cham-' her withthe hole 4 leading int-o it. 5, 6, 7

and 8 are outer rings between the shaft 1 and the box 2, and are securedwithin the box by the respective pins, 9 and 10, 11 and 12, 13 and 14,15 and 16. Fixed upon the shaft 1 and occupying the annular spacesformed by the outer rings 5, 6, 7 and 8 with the shaftand the box 2, arethe inner rings 17, 18, 19 and 20. Channels 21 and 22 assist indistributing the lubricant over the bearing surface 23. y

In the form of my invention, shown in Fig. 2, 24 is a shaft or journal,free to rotate in the journal bearing or box 25. 26 is a lubricantchamber with the hole 27 leading into it. 28, 29 and 30 are outer ringsbetween the shaft 24 and the'box 25 and are secured within the box 25 bythe respective pins31 and 32, 33 and 34, 35 and 36, Fixed upon the shaft24 and occupying the annular spaces formed by the outer rings, 28, 29and 30 with the shaft 24 and the box 25, are the inner rings 37, 38and39. Channels 40 and 41 assist in distributing the lubricant over thebearing surface 42.

In Fig. 3, 43 is a beam from which is suspended the hangers 44 and 45.46 and 47 are hanger boxes in which is journaled the shaft 48. Mountedupon the shaft 48 are the tight pulley 49 and the loose pulley 50.

outer rings. The loose pulley 50 is provided; with inner rings 63 and 64and outer rings 65 and 66. 67 and 68 are cant ducts 69 and 70.

In construction, the inner rings 17, 18, 19

plugs to the lubriand 20 of Fig. 1, 37, 38 and 39 of Fig. 2,

and 55, 56, 57, 58, 63 and 64 of Fig. 3, are all made to fit tight uponthe respective shafts 1. 24' and 48 are forced thereon into theirrespective position but have a free working fit with other contactingsurfaces. The outer rings 5, 6, 7 and 8' of Fig. 1, 28, 29 and 30 ofFig. 2,and 59, 60, 61, 62, 65 and 66 of Fig. 3, are made to fit tightwithin the respective box 2, box 25, hanger boxes 46 and 47 and hub ofloose pulley 50, and are forced intotheir respective positions, but havea free working fit with the other contacting surfaces. Screw pins, abovereferred to, are shown to illustrate one form of further securing theouter rings in the positions where they have been forced.

In operation, a lubricant is fed into a chamber provided for it andfinds its way between the contacting bodies through channels providedforits passage. In the rotation of the parts, the lubricant tends'to fly0E the inner rings and centrifugal action prevents it from backingtoward the axis of rotation along the passage out, between thecontacting surfaces. In connection with lubricant circulating devices,my invention will prevent flooding at the bearings, to

which it is applicable.

In Fig. 1, rings or devices 5 and 17 may be considered as constitutingone set, while 6 and 18' constitute another set, at or near one end ofthe contacting surfaces of the bearing, while at or near the other endof the bearing, two similar sets of rings or devices 19 and 7, 20 and 8,are shown. In Fig. 2, two sets of rings or devices are shown at or nearone end and one set is shown at or near the other .of the said'bearing.Additional sets of rings or devices similar in purpose and form to thosereferred to inthe figures may be provided between the contacting bodiesforming the bearing.

The details of construction of the devices shown in the drawings anddescribed in the above specification may be changed and yet The hangersuch modified devices may still come within the scope of my invention.Therefore, I do not wish to be confined to the special application ofthis lubricant retainer shown in the drawings and described in thisspecification.

Hence I claim:

1. A device adapted to retain oil on a bearing comprising two membersjournaled together, one of said members being circular in section andpositioned through the outer member, said outer member having one ormore annular recesses near each end thereof adjacent to the othermember, a collar positioned upon the inner member within each of saidrecesses, the walls of said recesses being lubricant tight and closelyenveloping said collars, whereby a lubricant extends from between thebearing surfaces of said members to envelop and contact said collars asa lubricant film, while contacting the inner walls of said recesses,means for supplying the lubricant to the device, one of said members andsaid collars cotiperating with the other of said members to neutralizeby centrifugal action the outward movement of the lubricant from betweenthe members, by maintaining the said lubricant film at each of saidcollars, substantially as set forth.

2. In a device of the character described, a bearing provided with anaxial bore with chambers at each end of the bearing concentric with thebore, a shaft rotatably mounted within the bore, spaced rings secured tothe bearing and disposed within the chambers at each end thereof, saidrings forming annular recesses with the bearing and with each other,spaced collars rigidly secured to the shaft for rotation therewith anddisposed within the recesses, a lubricant reservoir disposedintermediate the chambers of the bearing and having conduits forsupplying oil to the recesses inclosing said collars, the walls of saidrecesses being lubricant tight whereby the lubricant extends frombetween the bearing surfaces of the shaft and the bearing to envelop andcontact with the collars and rings as a lubricant film while contactingwith the inner walls of said recesses, the lubricant film 011 oppositesides of each collar being neutralized by centrifugal action to preventoutward movement of the lubricant from between the shaft and itsbearing.
